About this 3D model

I used cloud.netfabb.com to clean up the stl's (had a bunch of holes) and cut them into parts of 205x205x205 mm (fits on an ultimaker, guess why :P ) I was hoping to make something more generic but i guess you have to take a look at how you'd print these things anyway.... you can look at the fairly simple openscad files in the zip file and modify them for your printer size...
